Coal-fired boiler flue gas denitration catalyst separation device

Abstract

The invention discloses a coal-fired boiler flue gas denitration catalyst separation device which structurally comprises a clear liquid delivery pump, a clear liquid storage tank, a turbid liquid storage tank, a second interface level meter, a static mixer, a sedimentation separation tank, a liquid ammonia injection hole, an anti-corrosion conveying pipeline, a reaction kettle, a high-temperature-resistant temperature detector, a feeding hole, a heating tube, a temperature alarm, a first interface level meter, a heat exchanger, a bidirectional suspension separator, a membrane filter, a turbidliquid delivery pump, a sedimentation tank and a control valve; the clear liquid delivery pump is connected with the clear liquid storage tank through the anti-corrosion conveying pipeline; the staticmixer is connected with the turbid liquid storage tank through the anti-corrosion conveying pipeline; the bidirectional suspension separator is connected with the turbid liquid storage tank through the anti-corrosion conveying pipeline; the sedimentation tank is connected with the turbid liquid storage tank through the anti-corrosion conveying pipeline; and the heat exchanger is connected with the reaction kettle. By adopting the coal-fired boiler flue gas denitration catalyst separation device, the service life can be prolonged as the coal-fired boiler flue gas denitration catalyst separation device has an anti-corrosion function, and the internal reaction condition can be intuitively known.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a coal-fired boiler flue gas denitrification catalyst separation device. Background technique [0002] In a chemical reaction, the catalyst must keep in good contact with the reaction medium, so mechanical stirring or air blowing stirring is generally used in the reactor to promote the continuous renewal of the surface of the catalyst particles and the surface of the reactants, and the catalyst particles are in a suspended flow state in the reactor . The whole process is continuous production. After the reactants are converted into products, they are discharged from the reactor, and then the catalyst particles are also taken out of the reactor along with the products. In order to recycle the catalyst, solid-liquid separation must be carried out. Filtration and pressure filtration are generally used. During filtration, with the formation of filter cake, the resistance...
